The performance of 10671 horses in 10911 sport competitions was used to estimate the breeding value of the population of the Czech warm-blooded horses using the Best Linear Unibased Prediction method. The sport performance was estimated on the basis of the number of bad points (penalties) in jumping competitions. We analysed 252781 sporting results in the period 1991 – 2002. The estimations encompassed the fixed effects of sex, age, level of the competition and random effects of the breeder, rider, competition and the permanent environment. We compared the original and innovated calculations of the estimate of the breeding value of sport horses in the Czech Republic. We then compiled a list of estimated breeding values for stallions having 30 or more offspring and we compared the estimated breeding values with the results of the official system of progeny testing for performance in the Czech Republic.
